Xpost-BPics and makeup problem

I had my bpics scheduled for July 8th and Jaqueline Nicole was supposed to do my makeup. The other day my photog emails me and asks if we can do them on July 9th instead. I emailed Jaqueline and she told me that she has a wedding that day and cant to my makeup. I totally understand so I wrote to her again and told her I really want her to do my makeup for my bpics and asked her if there were any other days she could do it being that both the photog and I are flexible with dates. This was on sat. and I havent heard back from her. So I still havent rescheduled my bpics because I was waiting on Jaqueline to get back to me. Should I just pick a date and if she cant do my makeup get someone else to do it? I'm totally stressing this! Help!
